Asking for forgiveness is the successful remedy for getting rid of sins. This is why the Prophet ordered us to ask for the forgiveness of Allah, The Almighty, frequently.
The Prophet said: “O people! Ask for the forgiveness of Allah and repent to Him as I ask for the forgiveness of Allah and repent to Him one hundred times a day.”
Allah, The Almighty, is satisfied with the one who asks for His forgiveness as this person acknowledges his sin as if he says, “O Allah! I have made a mistake and I was negligent with Your rights as I wronged myself and the devil tempted me and my soul, which is a persistent enjoiner of evil, betrayed me. I relied on Your mercy, forgiveness, and forbearance. Now, I come to You while repenting and regretting, so forgive me, remove my sins and mistakes as I do not have any other Lord but You. O Allah! Even if my sins are grave, Your Forgiveness is greater and more comprehensive."

No doubt, You are the Oft-Forgiving, the Most Merciful).’” [Al-Bukhari]
